Allow? I'm pretty sure they don't need to allow anything. Media is becoming more potent at manipulating public opinion and the politician with the most donations can afford the best media. Whether his/her actual policies are in the material interest of the 99% voter is irrelevant.

Just note how much of the most recent election hinged on social signifiers instead of economic policy.

If the 99% don't have any power why would manipulating their opinions be worthwhile?
